What's Happening?
Researchers from the Leibniz Institute of Photonic Technology and Friedrich Schiller University have developed the Metafiber, a device that allows ultra-precise control of light focus within an optical fiber. The Metafiber uses a 3D nanoprinted phase-only hologram on a dual-core fiber to steer light by adjusting power between its cores. This innovation enables seamless focus shifts over microns without the need for bulky moving parts, offering compact and rapid tunable focusing capabilities.
